"I've come to like special relativity less and less. Mass increase, I think, is a purely theorethical effect of the theory, I'm not sure it has ever been proven empirically (and I have a hunch that those in the know don't even take it very seriously, it's just so absurd)."

Nonsense! The mass increase has been proven in experiments countless times, in fact it is measured thousands of times each day in particle accelerators. And believe me, physicists take this very seriously. I won't even bother to comment on the rest of your post. You really have to read up on the subject!

Great pic!

I don't have the time to read through this whole thread but I wanted to contribute something (which has perhaps already been said): It will cost far less to become a spacefaring civilization than what is spend each year by the nations of the world on military programs. We have the money to colonize space and, at the same time, feed the hungry, care for the environment and so on. Once private industry takes over no government will have to spend money on space development anyway.
One last thing: Without space colonization there will be no future for mankind.

You're a teenager and its shows. Hopefully you'll realize in time that your overly simplistic world view is a dead end...

As far as I know the probe is in perfect shape. There was a minor glitch some time ago but they resolved it. Cassini-Huygens will arrive at Saturn in 2004.

I don't see anything.

"Four other Aurora missions are planned over the next 20 years."

The most ambitious mission (sample return) is actually planned for as soon as 2011. The other three missions will serve as precursors for this mission in one way or another.
What comes next if the esa can really pull this off is anybody's guess. Aurora's long-term goal is sending humans to Mars by 2030.

By nuclear batteries you mean RTGs? That would be a good idea I think...

The first of the rovers is on its way! Link      

Take water and potash, add electricity and get - a mystery
By Robert Matthews, Science Correspondent

British researchers believe that they have made a groundbreaking scientific discovery after apparently managing to "create" energy from hydrogen atoms.

In results independently verified at Bristol University, a team from Gardner Watts - an environmental technology company based in Dedham, Essex - show a "thermal energy cell" which appears to produce hundreds of times more energy than that put into it. If the findings are correct and can be reproduced on a commercial scale, the thermal energy cell could become a feature of every home, heating water for a fraction of the cost and cutting fuel bills by at least 90 per cent.

The makers of the cell, which passes an electric current through a liquid between two electrodes, admit that they cannot explain precisely how the invention works. They insist, however, that their cell is not just a repeat of the notorious "cold fusion" debacle of the late 1980s. Then two scientists claimed to have found a way of generating nuclear energy from a similar-looking device at room temperature. The findings were widely challenged and the scientists, Martin Fleischmann and Stanley Pons, accused of incompetence, fled America to set up labs in France.

"We are absolutely not saying this is cold fusion, or that we have found a way round the law of energy conservation," said Christopher Davies, the managing director of Gardner Watts.

"What we are saying is that the device seems to tap into another, previously unrecognised source of energy."

According to Mr Davies, the cell is the product of research into the fundamental properties of hydrogen, the most common element in the universe. He argues that calculations based on quantum theory, the laws of the sub-atomic world, suggest that hydrogen can exist in a so-called metastable state that harbours a potential source of extra energy.

This theory suggests that if electricity were passed into a mixture of water and a chemical catalyst, the extra energy would be released in the form of heat.

After some experimentation, the team found that a small amount of electricity passed through a mixture of water and potassium carbonate - potash - released an astonishing amount of energy.

"It generates a lot of heat in a very small volume," said Christopher Eccles, the chief scientist at Gardner Watts.

The findings of the Gardner Watts team were tested by Dr Jason Riley of Bristol University, who found energy gains of between three and 26 times what had been put in.

In a written report, Dr Riley concluded: "Using the apparatus supplied by Gardner Watts and the procedure of analysis suggested by the company, there appears to be an energy gain in the system."

In tests performed for The Telegraph, the cell heated water to near-boiling, apparently producing more than three times the amount of energy fed into it.

Scientists admit to being astonished by the sheer size of the energy increase produced by the cell. "I've never seen a claim like this before," said Prof Stephen Smith of the physics department at Essex University.

"In the case of cold fusion, people talked about getting a 10 per cent energy gain or so, which could be explained away quite easily but this is much too big for that."

Prof Smith said he was sceptical about the theory put forward by the company. He conceded, however, that scientists had also been baffled by the source of energy driving radioactivity, as the key equation involved - Einstein's famous E=MC2 - had yet to be discovered.

According to Prof Smith, if there is a flaw in the company's claims, it lies in the measurement of the amount of electrical energy pumped into the cell. It is possible that, as sparks pass between the electrodes, there is an energy surge which would not be picked up by the instruments measuring the electrical input.

Prof Smith said: "This needs to be very carefully checked, as there could be far more energy going in than the makers think."

Prof Smith's views were echoed by Dr Riley, who said: "There's no doubt that there was a heat rise but I'd like to see a more thorough investigation of the electrical energy supplied into the cell."

While many scientists are trying to solve the mystery of the thermal energy cell, its huge commercial potential has already caused interest.

Cambridge Consultants, one of Britain's most prestigious technology consultancies, has teamed up with Mr Davies and his colleagues to develop a working prototype. "We've had a multi-disciplinary team working on this, and we're perplexed," said Duncan Bishop, head of process development at Cambridge Consultants.

"We are offering to risk-share on it, as it will need about ?200,000 to prove the principle behind it."

According to the Gardner Watts team, it will take about six months to carry out tests putting the reality of the effect beyond all doubt. The company then plans to develop a prototype capable of turning less than one kilowatt of electrical power into 10 kilowatts of heat.

Mr Davies said: "The technology could be licensed by a company making household boilers for the domestic market. " He added that the plan is to have the first thermal energy cell devices on the market within two years.

What do you think about this? As I've indicated earlier I think cold fusion is real and that it will someday (within the next ten to twenty years) be accepted by the so called 'scientific community'. This new device is not cold fusion but it may be useful in showing the world (and overly conservative scientists) that a lot remains to be discovered...

I don't think we'll run out of oil any time soon and when the time comes we'll already have phased out fossil fuels, there are countless alternatives.

I second that. That paragraph by Diderot has wetted my appetite; I'll start reading the entire thread right now.
